Product Description


Vehicle Mounted Signal Jammers For Security 300m Long Jamming Distance 0

Working frequency 20 to 6000MHz Vehicle Mounted Jammer with long jamming distance of 300m


1. Description

ZD-GR500 vehicle frequency jamming system is the latest generation system which applies digital interference code jamming and control technology. This jamming system can jam all kinds of wireless communication within 20 to 6000MHz and has long jamming distance of 300m.  It classifies standards of different signal and jams them by using corresponding optimal methods which achieves the best jamming effect. It overcomes common weakness of jammer from other companies such as weak jamming effect espeically for walkie-talkie signals. The advanced technology also makes jammer use low power to cause long jamming distance. It reduces damage of high temperature and strong high frequency radiation on passengers’ health markedly. The core parts of ZD-GR500 are designed with all digital circuit.  People can use the displayer to set jamming frequency bands. The antenna system and vehicle power supply are designed with optimal methods which improves reliability and utility of the jamming system. This system can be used to protect anti-terrorism staff and public security personnel.


2. Specification



Input Voltage:

AC220V Total Output Power: 500W
Jamming Distance: 300m;  75m(for 100distance between two walkie-talkies) Weight Of Main Unit: 148Kg
Dimensions(mm): 1000(W)´580(H)´606(D) Working Temperature: -20℃~55℃



3. Applications


This jammer can be widely used by departments of police, antiterrorism and country security protection.

  • It can prevent activation of remote controlled bombs and stop the terrorism activities.

¨ It can prevent terrorism attack and harassment of drones.

¨ For some VIP convoy, the system protects them during their traveling and ensures security of their parking area.

¨ For the emergency security protection during mass disturbances and large meeting, it can block the mobile signal in a large range to stop the extension of turbulence.

  • When it is used in scenes of illegal gambling or sell drug, it can block mobile phone signal to stop the communication between criminals.
  • When it is used in important department of country security and military, it can block wireless signal.


4.  Advantages


¨ The system applies optimal advanced jamming and control technologies. It has the best jamming effect in each frequency band. The jamming radius is 300m while the transmitting power is only 500W. For walkie-talkie, the jamming distance is 75m while the distance between two walkie-talkie is 100m.

..It has more completed working frequency from 20MHz to 6GHz than similar products of other company. It does not lack any important frequency bands such as walkie-talkie bands which ensures effectiveness of signal jamming. And it can be used to jam remote-control bomb which work in the walkie-talkie bands.

¨ Each frequency band of the system can work individually. The user can select jamming several bands and set some other bands for communication.

¨It has functions of displaying work state (band, output power, battery percentage), error warning (over-voltage, over-current, overheat) and so on.

¨ The RF output power can be adjusted as requirement. It will also adjust jamming distance of the system.
